[0073] The right end of the left front locking bolt 60 is screwed into the left front threaded hole 503; the left end of the right front locking bolt 70 is screwed into the right front threaded hole 504; when the left front locking bolt 60 and the right front locking bolt 70 are loosened outward, the angle of rotation of the mattress supporting plate 50 around the left rotation shaft 501 and the right rotation shaft 502 can be adjusted.

[0074] Based on the above, it can be clear that the present application is mainly used as a head and foot height adjustable nursing bed 1000 in specific implementation.

[0075] Specifically, in the application of the present application, the present application is assembled according to the above-mentioned structure, and the mattress is placed on the mattress supporting plate 50 and the bed sheet is laid.

[0076] On the one hand, referring to Figure 9 For patients who need to meet the head high and foot low sleeping position, such as patients who need to eliminate upper limb or head swelling to promote blood flow to the lower limbs, the left front locking bolt 60 and the right front locking bolt 70 can be loosened outward to make the mattress supporting plate 50 rotate around the left rotation shaft 501 and the right rotation shaft 502 to force its front end to be in a high position and its rear end to be in a low position, and then the left front locking bolt 60 and the right front locking bolt 70 are tightened to re-fix the mattress supporting plate 50, so that the patient lying on the present application will have the head in a high position and the feet in a low position, so that the present application meets the head high and foot low sleeping position of the patient.

[0077] On the other hand, referring to Figure 10As shown, for patients who need to meet the head low foot high position, such as patients who need to eliminate lower limb swelling to promote blood flow to the head, the left front locking bolt 60 and the right front locking bolt 70 can be loosened outwardly to make the mattress support plate 50 rotate around the left rotating shaft 501 and the right rotating shaft 502 to force the front end to be in a low position and the rear end to be in a high position, and then the left front locking bolt 60 and the right front locking bolt 70 are tightened to fix the mattress support plate 50 again, so that the head of the patient lying on the application is in a low position, and the feet are in a high position, so that the application meets the head low foot high position of the patient.

[0078] Obviously, for the application of the application, the entire mattress support plate 50 is flipped to a certain inclination to meet the head low foot high position of the patient, or to meet the head high foot low position of the patient, after being flipped to a certain angle, the upper surface of the mattress placed thereon presents a flat inclined surface, compared with the traditional bed support plate which is divided into front and rear support plates, the front end of the front support plate needs to be lifted separately to meet the head high foot low position of the patient or the rear end of the rear support plate needs to be lifted separately to meet the head low foot high position of the patient, resulting in a certain included angle at the middle joint, so that the patient cannot lie straight, resulting in uncomfortable lying, and the application does not have related problems. The entire mattress support plate 50 of the application is flipped to a certain inclination, and the upper surface of the mattress placed thereon presents a flat inclined surface, so that the patient lies comfortably, especially for lying straight sleep.

[0079] Further, the above optimization design makes the whole application have strong practicality, strong flexibility and strong adaptability, and has good use effect.

[0080] Further, in specific implementation, Figure 2 and Figure 6 As shown, according to an embodiment of the application, the inner wall of the left front arc-shaped groove 302 uniformly expands from top to bottom to form a plurality of left front clamping grooves 3021, and the inner wall of the right front arc-shaped groove 402 uniformly expands from top to bottom to form a plurality of right front clamping grooves 4021, and the plurality of left front clamping grooves 3021 and the plurality of right front clamping grooves 4021 are one-to-one left and right from top to bottom.

[0081] Among them, the middle part of the left front locking bolt 60 outwardly protrudes to form a left front clamping convex 601 which is adapted to be clamped into any left front clamping groove 3021; and the middle part of the right front locking bolt 70 outwardly protrudes to form a right front clamping convex 701 which is adapted to be clamped into any right front clamping groove 4021.

[0082] Preferably, in the technical solution, according to one embodiment of the utility model, the left front clamping convex 601 left and right length is less than the left front screw hole 503 left and right length and the length between the middle part of the left front locking bolt 60 and the right end thereof, so that when the left front locking bolt 60 is screwed to the left to make the left front clamping convex 601 protrude out of the left front clamping groove 3021, the right end of the left front locking bolt 60 is still retained in the left front screw hole 503.

[0083] And preferably, in the technical solution, according to one embodiment of the utility model, the right front clamping convex 701 left and right length is less than the right front screw hole 504 left and right length and the length between the middle part of the right front locking bolt 70 and the left end thereof, so that when the right front locking bolt 70 is screwed to the right to make the right front clamping convex 701 protrude out of the right front clamping groove 4021, the left end of the right front locking bolt 70 is still retained in the right front screw hole 504.

[0084] Therefore, when the bed mattress support plate 50 needs to be adjusted as a whole, the left front locking bolt 60 is screwed to the left to make the left front clamping convex 601 protrude out of the left front clamping groove 3021, and the right front locking bolt 70 is screwed to the right to make the right front clamping convex 701 protrude out of the right front clamping groove 4021, and then the left end of the left front locking bolt 60 and the right end of the right front locking bolt 70 are held and forced in the up and down direction to rotate the bed mattress support plate 50 to make the front end of the bed mattress support plate 50 be raised or lowered to a predetermined height, so that the left front clamping convex 601 is aligned with the left front clamping groove 3021 at a certain height position, and then the left front locking bolt 60 is screwed to the right to make the left front clamping convex 601 on it protrude into the left front clamping groove 3021 at the corresponding height position, and then the right front locking bolt 70 is screwed to the left to make the right front clamping convex 701 on it protrude into the right front clamping groove 4021 at the corresponding height position, so that the front end of the bed mattress support plate 50 is fixed to the required predetermined height, and the bed mattress support plate 50 is connected and fixed to a certain inclination, and then the utility model is used.

[0085] It should be noted that the tightening order of the left front locking bolt 60 and the right front locking bolt 70 is not important. That is, the right front locking bolt 70 can be tightened to the left first so that the right front locking protrusion 701 extends into the right front locking groove 4021 at the corresponding height position. Then, the left front locking bolt 60 can be tightened to the right so that the left front locking protrusion 601 extends into the left front locking groove 3021 at the appropriate height position. In this way, the front end of the mattress support 50 can be easily fixed to the required preset height so that it is connected and fixed at a certain angle. When there are two medical staff, the tightening operation of the left front locking bolt 60 and the right front locking bolt 70 can be operated simultaneously by the two medical staff.

[0086] Obviously, by setting multiple left front locking grooves 3021 and multiple right front locking grooves 4021, the left front locking protrusion 601 on the left front locking bolt 60 and the right front locking protrusion 701 on the right front locking bolt 70 are correspondingly locked, so that after the front end of the mattress support plate 50 of this application is raised or lowered to the required preset height, its fixed stability is good and it is not easy to shake up and down, so that this application has good reliability.

[0087] Furthermore, in specific implementation, it should be combined with Figure 1 , Figure 4 , Figure 5 and Figure 8 As shown, according to one embodiment of the present invention, this application also includes a left rear locking bolt 80 and a right rear locking bolt 90 for locking and fixing the mattress support plate 50;

[0088] Wherein, the rear end of the left connecting plate 30 has a left rear arc-shaped groove 303 with the center of the left turning hole 301 as the center, which penetrates the left and right end faces; the rear end of the right connecting plate 40 has a right rear arc-shaped groove 403 with the center of the right turning hole 401 as the center, which penetrates the left and right end faces.

[0089] Furthermore, the left rear locking bolt 80 passes through the left rear arc groove 303 with an interference fit from left to right and is screwed into the rear end of the left side of the mattress support plate 50; the right rear locking bolt 90 passes through the right rear arc groove 403 with an interference fit from right to left and is screwed into the rear end of the right side of the mattress support plate 50.

[0090] Specifically, in this application, according to one embodiment of the present utility model, the rear left side of the mattress support plate 50 has a left rear screw hole 505 opening to the right, and the rear right side of the mattress support plate 50 has a right rear screw hole 506 opening to the left.

[0091] The right end of the left rear locking bolt 80 is screwed into the left rear threaded hole 505, and the left end of the right rear locking bolt 90 is screwed into the right rear threaded hole 506; when the left front locking bolt 60, the right front locking bolt 70, the left rear locking bolt 80 and the right rear locking bolt 90 are loosened outward, the angle of the mattress support plate 50 rotating around the left rotating shaft 501 and the right rotating shaft 502 can be adjusted.

[0092] Therefore, by arranging the left rear locking bolt 80 and the right rear locking bolt 90, when they are tightened inward synchronously with the left front locking bolt 60 and the right front locking bolt 70, the fixation of the mattress support plate 50 after being turned to a certain inclination can be better improved, so that the application is more reliable in use.

[0093] Conversely, when the left front locking bolt 60, the right front locking bolt 70, the left rear locking bolt 80 and the right rear locking bolt 90 are loosened outward, the mattress support plate 50 can be rotated around the left rotating shaft 501 and the right rotating shaft 502 by a preset angle, so as to facilitate the adjustment of the inclination thereof.

[0094] Further, in specific implementation, referring to Figure 3 and Figure 7 According to one embodiment of the application, the inner wall of the left rear arc-shaped groove 303 is uniformly expanded from top to bottom to form a plurality of left rear clamping grooves 3031, the inner wall of the right rear arc-shaped groove 403 is uniformly expanded from top to bottom to form a plurality of right rear clamping grooves 4031, the plurality of left rear clamping grooves 3031 and the plurality of right rear clamping grooves 4031 are one-to-one corresponding from top to bottom and left to right, and the height of the plurality of left rear clamping grooves 3031 and the height of the plurality of right rear clamping grooves 4031 are one-to-one corresponding and same as the height of the plurality of left front clamping grooves 3021 and the height of the plurality of right front clamping grooves 4021.

[0095] The middle part of the left rear locking bolt 80 outwardly protrudes to form a left rear clamping protrusion 801 adapted to be clamped into any one of the left rear clamping grooves 3031, and the middle part of the right rear locking bolt 90 outwardly protrudes to form a right rear clamping protrusion 901 adapted to be clamped into any one of the right rear clamping grooves 4031.
